Application filed September 11, 1905. Serial No. 277,850.

T0 all whom 'it may concern:

Be it known that I, EDWARD SEITZ, citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Vapor-Lamps; and I do hereby declare that the following is a full, clear, and exact description `of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to improvements in vapor lamps.

One of the objects of the invention is to provide a vapor generator immediately above the burner and having connected directly thereinto a hydro-carbon fluid conducting member for introducing the fluid immediately into suchV generator.

Iam aware thatv it is. not new to provide a` vapor generator immediately above the burner lnor to introduce` fiuid into a gener.- ator, -but the lparticular arrangement which I show and describe lierein-I'believe to be new. In devices of this character there is always a vapor jet orifice for discharging vapor into a conducting member communi.

cating with the burner, there also being an air space between the orifice and the conducting member to provide for proper mixture of vapor and air, and it is my purpose in connection with the air space just mentioned, as one of my objects, to provide a conducting member by which tocarry away from the air-space, and from the jet orifice, any fluid that may not have become vaporized, such member leading the fiuid away from the vicinity of the burner to thereby avoid the danger of possible ignition of th fluid from the burner.

It is also an object to provide a peculiar form of cast member through which to convey the vapor and through' which also to convey the fluid before being formed into vapor, the fluid being heated from the heated vapor as it passes to the burner, all of which will be pointed out in the accompanying claims.

In the appended drawing, Figure 1 is an elevation of my improved lamp. Fig. 2 is a sectional elevation of vaporizing device. Fig. 3 is a top view of portion of a needlevalve and mixing chamber and connection therebetween. tion of a mixing chamber and gasolene-conduit. Fig. 5 is a rear Velevation of vapor- Fig. 4 is a sectional eleva-- mixer showing position of certain parts for permitting removal of a connection between the mixer and needle-valve shown in Fig. 3. Fig. 6 is an elevation of a portion of the top of the lamp-frame showing a suspending hook for the lamp.

.My lamp frame consists preferably of lengths of tubing and light tubular castings which are easily and quickly assembled and constitute a frame that is low in cost and quite rigid.

I provide a hook as at A by which to suspend the lamp, and into this is screwed a suitable length of tubing B, the latter being in turn screwed into a casting C which forms the mixing chamber for the vapor as will be described later. Into the lower end of said ing D having at. its opposite end a cast j elbow, or goose.-neck,I yinto which said tube is. also screwed. The upturned freelend of the elbowf E has the u'sual- Bunsen burner (not indicated) surmounted by a -mantle F. It hasbeen the practice heretofore to employ a length of tubing and bend it in the desired manner to form a frame of the shape best suited for a lamp frame. But this process is costly because it consumes much time and for the further reason that many of the tubes are broken in` the attempt to bend them. It has therefore been my object among others, to produce a frame that is of low cost and quickly and easily put together. The castings are all of uniform size and shape, merely needing a thread or two into which to screw the uniform lengths of tubing taken from stock. It will be seen that a frame can `be put together in a fraction of the time necessary to make the older forms referred to.

I have referred to the casting C as a mixing chamber. It is also a gasolene conduit and may be understood by reference to Fig. 41. It has a passage a opening at one side of the casting through an extension C', and extending inward and downward to open into the tube D, in Fig. 1, already described. Cast with the said member C are two horizontal extensions C2 and C3 within which is a continuous passage Z) which extends around the passage a as shown in Fig. 4 there being a wall C4 separating said passages. Connected to the extension yC3 is a pipe Grandcontrolling valve H, while con.- nected into the extension C2 is a horizontal tube J forming-part of a vapor-generator K stationed immediately above the mantle F as shown. Said generator, as shown in Fig. 2, consists of a vertical hollow member. having suspended therefrom and preferably cast therewith, an open torch L and radiating heat conducting fingers M. The said member K has a bottom N to form a closed chamber. Above the tube J and also cast with member K is a tube O within which is a needle-valve P for regulating the opening of and for closing an aperture Q in the closed end R of the said tube O. The member K is preferably provided with an asbestos filling S, while the needle-valve P is surrounded with a winding of wire gauze or other form of strainer. The torch L is likewise provided with asbestos or other material that will not burn but will absorb a fluid such, for instance, as gasolene or alcohol. The needle-valve is located just opposite the passage a of the casting C and the vapor passes from the former into the latter under pressure and thence through the pipe D and casting E to the mantle F. As in common practice the jet-orifice Q is separated from the mixing chamber a by an air space, see Fig. 8, whereby the vapor issuing from such orifice can take air into said mixing chamber with it. ln some instancesthis air space is unprotected and in others some sort of means is provided for preventing strong air currents from striking` the vapor at this point. I have provided in the present instance a new form of protecting member indicated by the letter T and consists of a cast sleeve having an elbow U formed therewith terminating in a downturned tube V. The sleeve is provided with a notch W for receiving a lug X on the extension C upon which the sleeve is designed to slip, the lug serving` to sustain the sleeve in a stationary position. Provision is made for removing the sleeve T from the lamp and this is accomplished by slipping said sleeve back upon the member O as shown in Fig. 3, then the generator K is swung on the member C by turning the member J in the latter to carry the said member O away from the member C as shown in Fig. 5, the device being viewed from the back of the lamp, the parts G and H being removed from the extension C3. By turning the member J a sufficient distance it will be seen that the sleeve T can be carried clear of the mixer C so as to be slipped on and off when desired.

The advantage in the closed sleeve with the tube V is, that no drafts or air currents can possibly affect the vapor jet but at the same time the needed air for proper combustion at the mantle will be drawn in through said tube V. A further advantage in providing the said tube is that any gasolene not vaporized, should it reach the jet orifice for any reason will fall upon the interior surface of the sleeve and by gravity will be drained out through the tube V far from the mantle, thus minimizing all danger of igniting therefrom. By providing one casting for the vapor ejected from the jet-orifice and the gasolene as it comes from the source ofsupply, the heated vapor makes the said casting intensely hoty and by having the gasolene pass through the heated metal on its way to the generator it is in better condition to be quickly vaporized. In practice the gasolene is admitted to the casting C by means of the controlling valve H, passes through the conduit into the tube J and thence into the generator K. The torch having previously been supplied with a small quantity of combustible fluid is ignited the flame therefrom serves to quickly raise the generatorl to a high temperature assisted by the radiating ngers M which conduct the heat to said generator. The fiuid having entered the latter is distributed through the asbestos filling end subjected to the intense heat and immediately vaporized and forced by its own expansion upward into and through the needle-valve or jet orifice Q. The vapor is forced across the air space within the sleeve T into the mixing chamber or passage e from whence it passes downward eventually reaching the mantle where it is ignited from the still burning torch above. The casting C through whose passage a the vapor must pass is quickly raised to a high temperature so that the gasolene thereafter passing through the passage b is heated to a high degree before entering the generator where it is more readily converted into the combustible gas. The asbestosserves to strain the particles of foreign matter from the fluid and holds back the paraffin always found in that material, and furthermore the fluid by being carried through the asbestos is quick y spread and by filling the space therein is quickly heated and vapo-v rized and rendered intensely hot. An advantage in having the jet-orifice above the inlet of gasolene at J to the generator is that the resulting vapor is carried to a high elevation and consequently there is little chance for fluid to pass out of the jet orifice with it and is in better condition for burning at the mantle.

An advantage in the method of constructing the lamp frame which T have not heretofore mentioned is the fact that any part of said frame can be removed at any time even by aninexperienced person and a swab pushed thr ugh every part of said frame to remove all sediment that may collect therein, whereas in a frame of a single length of tubing this is not practicable. It is to be observed that any and every portion of the frame and fittings throughout the lamp can be easily reached and cleaned.

I am aware that others have produced vapor lamps wherein the vapor is carried od to the' burner fromk above the point where` the gasolene is entered by which means, as in mine, the vapor is consequently in drierA form but' these devices do not have in conjunction with the arrangement mentioned, the peculiar form of cast member C I have described byv which to initially heat the fluid before it enters the generator. In my arrangement the single casting C has the two passages a and b separated by a thin wall and each extending` at right angles to one another, the super-heated vapor heating the fluid to a high degree as it passes partially around the vapor passage, the solid metal being kept heated by the hot vapor.

I am also aware that' on this class of lamps a sleeve hasbeen employed between the outlet end of the generator and the vapor-receiving tube in the position in which mine is shown but a sleeve having the horizontally positioned tube V with a downturned outer end has not to my knowledge been used.

In my lalnp the vertical portion K of the generator being directly over the burner is heated thereby and the flame from its torch is readily communicated to the said burner as the vapor arises around it. The inlet or supply pipe J is also over the burner and is of large size thereby carrying a considerable bulk of gasolene distributed through the filling thereof. In this as well as the member K the fluid is highly heated and vaporized and strained as already stated then passing to the member O which is also of large size thereby providing for a large and unfailing body of vapor under considerable pressure.

By having J and O separate pipes a larger bulk of gasolene can be passed to the generator and consequently a greater amount of vapor can be made and held constantly in reserve which can be drawn from by the burner as needed through the jet orifice. Furthermore, these members J O being separate provide for a larger heating area than would otherwise result by any other oonstruction.

Therefore I claim 1. In a vapor lamp the combination of a vertically positioned hollow vaporizing member provided with a torch at its lower end, a horizontally disposed lower member having a single bore or passage and connected at one end into the said vertical member, and connected at its opposite end with the fluid supply, a second separate upper horizontally disposed member adjacent to the first and having a single bore and connected at one end into the said vertical member and provided with a vapor et orifice at its other end, both said lower horizontally disposed member and the vertical member having a filling therein for the purposes set forth, a vapor burner positioned directly beneath the vertical member and ignited from its'toich, a member for carrying vapor to thfburner from the' jet orifice inthe upper of said horizontally disposed members, there being an opening in the vaporca'rrying member opposite the jet orifice, a valve forv controlling the supplyy of fluid through the lower of the horizontal members to the vertical member, and a valve for controllingv the vapor jet orifice substantially as set forth.
